    Title: Basic Model of a Neutral Atom
    Type: Text Slide
    Content:
    • Electrons (-) orbiting nucleus of protons (+) and neutrons.
    • Same number of electrons as protons; net charge = 0.
    • Atomic number (number of protons) determines element.
    • Mass number (protons + neutrons) gives mass in terms of 1/12th mass of Carbon atom.
